Title: Mold lockup mechanism
IPC: B22D17/26
Filed: 1977-11-11
Abstract: An injection molding machine has two stationary platens interconnected by tie bars and an immediate third platen which is movable on the tie bars. Separable mold portions are mounted respectively on one of the stationary platens and the third platen so that reciprocating movement of the third platen along the tie bars opens and closes the mold portions. A pair of toggle linkage mechanisms positioned at opposite sides of the machine and connecting with the movable third platen and one of the other platens are used to lockup the mold portions when the linkages assume their toggle positions. To move the toggle mechanisms into the toggle positions, a crosshead on slide rods connects with the mechanisms and is pushed away from the third platen at lockup by two piston and cylinder assemblies extending between the platen and the crosshead. The positioning of the cylinders and crosshead minimizes the overall length of the molding machine and permits mold lockup to be triggered more accurately.

Title: Apparatus for braking systems incorporating a pressure-control device for antiskid control
IPC: B60T8/50
Filed: 1978-01-17
Abstract: A throttling arrangement for braking systems with antiskid control disposed between the pressure-control device and the wheel braking cylinders.

Title: Automatic kinescope bias control circuit
IPC: H04N5/14
Filed: 1979-10-11
Abstract: Apparatus for automatically controlling the bias of an image reproducing color kinescope in a system incuding a plurality of video driver stages for supplying image representative video signals to respective intensity control electrodes of the electron guns of the kinescope. The output of each driver stage is coupled to an operating supply voltage via a load impedance. The electron gun currents (e.g., cathode currents) are sensed during image blanking intervals of the video signal to provide respective control voltages representative of the electron gun blanking current levels. The control voltages are respectively applied to control the output operating voltage of each driver stage, and thereby the electron gun bias, in a manner to reduce deviations of the blanking current level from a normally expected level. In one embodiment, each driver stage comprises a transistor with a video input base electrode, and a collector output electrode coupled to an electron gun. The control voltage is applied to the collector circuit of the transistor for varying the quiescent current through the load impedance and the collector quiescent output potential independent of the video signal, to thereby vary the electron gun bias in a direction for reducing the blanking current. Interaction between the control voltages and video signals is minimized, and the apparatus is suitable for use with kinescopes having separately energized grids or with kinescopes having grids energized from a common source.

Title: Inlet air swirl control means for I.C. engines.
IPC: F02B31/06
Filed: 1982-08-27
Abstract: Inlet swirl control means for I.C. engines includes, for each inlet port (12, 12 min ) of an engine, a movable insert sleeve (35, 35 min ) slidingly mounted in the inlet passage (13, 13 min ) of the port as a liner for the passage, the or each insert sleeve having a profiled tongue (37, 38 min ) at its inner end which projects to a variable extent into the bowl (14, 14 min ) of the port.

Title: Flight calculation apparatus
IPC: F41G5/08
Filed: 1982-11-30
Abstract: The device is for deriving the distance, esp. the crossing distance, of a point on a straight uniform flight path, and derives the angle (alpha) in the flight plane from the initial elevation, current elevation (epsilon) and transverse angle (beta). Flight plane angle information is passed to a computer unit (12)  which derives the modular speed and flight variables from which  actual distance, crossing distance and speed direction w.r.t. an optional ternary reference system can be obtained. - The required data is optimally filtered by a group of computation units (14-16). A fire direction and targetting system (P56) receives analogue speed and angle information and supplies a voltage corresp. to the crossing distance for rotor computations. An error value is filtered (16) and fed to a controller (18) with the crossing distance value. An imaginary crossing distance value (Rtx) is generated for the initial phase. (1/2) DEAB- DE3244879 C The electronic ranging device provides the momentary distance of a flying object travelling in a straight line, from the observation point using successive values for the observation angle (E) and the azimuth angle (5) provided by a target tracking device and the known or calculated velocity of the object. - Pref. the instantaneous distance is calculated in a processor (10, 12) using a given sinusoidal function in terms of the elevation and azimuth angles and the velocity. The instantaneous distance can then be used to calculate the perpendicular distance of the flight path from the observation point using a second trigonometric formula.
